Ancient asteroid may hold clues on water’s origin on Earth

00:00 After a journey spanning over 96 kilometers, scientists now study fragments of an ancient
00:05 asteroid that could explain water's origin in our home planet.
00:10 V-Way's Arash Rabasadi has this story.
00:14 We begin this week with what could be the future for sustainable farming on Earth and
00:19 in space.
00:20 Paris and Los Angeles-based biotech company Interstellar Lab designed the BioPod.
00:26 The company's founder says BioPod allows farmers to localize the production of common
00:31 crops that would otherwise require global supply chains and therefore reduce greenhouse
00:36 gases that come with long journeys.
00:39 "Brewing vanilla, for instance, here, then this is when the BioPod makes a lot of sense.
00:44 And so it's reduced the CO2 impact of making the travel of the ingredients from one country
00:49 to the other.
00:50 We optimize the consumption of water.
00:53 So compared to traditional agriculture, it's like 99 percent of the water is recycled and
00:57 reused.
00:58 We take CO2 from the atmosphere to enrich the level of CO2 inside the bubble."
01:03 By stacking the units, Interstellar Lab says it can reduce the footprint for growers while
01:08 providing a more efficient space to grow crops in units that go up instead of out.
01:14 In collaboration with NASA, a space-based version of BioPod is scheduled for use on
01:18 the Moon by 2027.
01:21 The Reuters news agency reporting Interstellar Lab founder Barbara Balvisi will attend the
01:26 COP28 climate conference to raise interest and money for the project.
01:31 When commercial production begins, each unit will sell for $350,000.
01:37 In other news, the dust and fragments in these still images come from the 4.5 billion year
01:43 old asteroid Bennu.
01:46 NASA's OSIRIS-REx spacecraft collected the samples in October 2020.
01:51 After a journey of more than seven years, it landed at the Utah Test and Training Range
01:55 military facility.
01:57 Researchers say they found water trapped in the fragment, which may be a clue as to how
02:02 water came to Earth.
02:03 "When the Earth formed, it probably formed really, really hot and most of the water would
02:09 have evaporated.
02:10 So it could be that the Earth got its water because it was pummeled by asteroids like
02:15 Bennu that provided this water to the Earth's surface."
02:20 Russell added that Bennu is perhaps the most hazardous threat to Earth in our solar system,
02:25 so part of the research is to better understand its orbit and composition if scientists ever
02:31 had to find a way to deflect it.
02:33 Regardless, Russell says it will take months and years to unlock the many questions scientists
02:38 have about this ancient asteroid.
02:41 Finally this week, if you've ever had a rough day at the office, try losing your tool bag
02:46 in Earth's orbit outside the International Space Station.
02:50 That's what happened in early November when NASA astronauts Jasmine Mogbele and Laurel
02:55 O'Hara lost theirs.
02:57 The bag was visible with just binoculars and joined a long list of space junk orbiting
03:02 our planet.
03:03 Arash Arbasadi, VOA News.
03:05 way to use.
